President Donald J. Trump announced on Truth Social on January 29, 2026, that the United States is immediately decertifying all Bombardier Global Express aircraft, and all other Canadian-made aircraft, and will impose a 50% tariff on Canadian aircraft sold in the U.S. if Canada does not quickly reverse its refusal to certify Gulfstream’s G500, G600, G700, and G800 business jets. Trump framed the move as direct reciprocity for Canada’s “wrongful, illegal, and steadfast” certification block on Gulfstream, calling the Savannah, Georgia-based company a “Great American Company” and warning that the situation must be corrected immediately.

The president’s post detailed the escalating trade dispute over business jet certification, accusing Canada of refusing to approve Gulfstream’s ultra-long-range jets despite their global certification and FAA approval. Trump described the Gulfstream jets as “one of the greatest, most technologically advanced airplanes ever made” and said Canada was effectively prohibiting their sale in its own market.

Trump announced two immediate actions:

  • Decertification of Bombardier’s Global Express series—including the 5500, 6500, and 7500 models—and all other Canadian-manufactured aircraft.
  • A 50% tariff on any Canadian aircraft imported into the U.S. unless Canada reverses its certification denial for Gulfstream jets.

The dispute revolves around bilateral aviation certification reciprocity under FAA–Transport Canada agreements. Gulfstream, a General Dynamics subsidiary, claims Canada has delayed or denied certification for technical reasons that U.S. officials view as protectionist or politically motivated, possibly linked to broader trade tensions over dairy, lumber, and digital services.

Bombardier, headquartered in Montreal, depends heavily on U.S. sales for its Global series. A 50% tariff would sharply raise costs for American buyers, likely cutting demand for Bombardier jets while giving Gulfstream a competitive advantage in the ultra-long-range private jet market.
